What to write about

• Corrections. If something on the site is factually wrong, this is the most useful message you can send. Point at the page and say what is wrong — it will be checked and fixed.
• Tool problems. A test that will not start, a key that does not register, a score that looks impossible. Mentioning your browser and operating system makes it far easier to reproduce.
• Suggestions. A test you expected to find here and did not.
• Business enquiries. Partnerships, licensing, or anything commercial.

What to expect

Everything gets read. Replies are not guaranteed, and this is not a support desk for third-party software — questions about a specific auto clicker or keyboard you downloaded elsewhere are best directed to whoever makes it.

Data access and deletion requests can be made the same way. The privacy policy explains what is and is not collected, which for most visitors is very little.
